Ringworm is a common and highly contagious fungal infection in cats that causes significant welfare problems in shelters and can persist without proper treatment protocols.
Ringworm causes ongoing discomfort and itching that significantly affects cat quality of life, especially in shelter environments where stress already compromises immune function. The chronic nature of untreated ringworm — causing hair loss, crusty lesions, and persistent irritation — represents unnecessary suffering when effective treatments exist. The greatest welfare concern is that some shelters euthanize treatable cats rather than implementing systematic treatment programs. Shelter ringworm protocols that enable treatment and adoption save lives and prevent ongoing animal suffering.
